Various symbols and totems have become associated with Calontir as can be seen in our Arms, badges, awards and order names.

The Cross of Calontir

The Cross of Calontir is heraldically known as a Cross of Calatrava.
It is found on the Kingdom Arms (pictured), the Kingdom Ensign (which is also used as a populace badge and standard augmentation), and multiple award badges including the Order of the Calon Cross.
The story of how it came to be on the Arms of the Kingdom....

The Falcon

From Brock Hanke - A piece of info for you [Ixtilixochitl de los Indios] fighting under the falcon banner for King Chepe. Chepe was the person who originally put forth the idea of the falcon being Calontir's token animal. This was at a Witan meeting during his first rulership (he was a Warlord in the Region or a Prince in the Principality, I forget which, maybe both, but BEFORE the Kingdom). We were trying to decide what totem animal to use, and he just said, "Falcon. I want it to be the Falcon." None of us were really worked up about any of our own choices, so we just said, "OK" and that was it.
The Falcon, as noted above, is on the Kingdom war banner. It also appears on the Kingdom War Badge (used by both Calontiri and allies at war), and various awards.

I had heard, years ago and from some sources, that the need for a warlike totem animal was one of the impetuses behind Baron Steven creating the demo-bison. - Christian d'Hiver
The story of Argent, the Silver Demo-Bison is too long for here, and is not my right to pass on. It's Stephen's. My understanding is that the story is currently being written up and will be published. I am not CERTAIN about that, though. - Brock Hanke
